I wonder how many of the people whining about this law were ones that supported the cafe standards. If I were a vindictive individual I would go back and check, just to embarass some of the more vehement protestors. Of course, I can understand the viewpoint of only complaining when something actually affects you, but folks let this boat sail a long time ago when they started letting the government put limits on things like fuel economy. It's just a question of when they start putting quotas on electricity usage - because eventually they will.
CAFE standards have been around for almost 40 years with no quota on gasoline consumption in sight. Your conclusion is not supported by the facts.
